I'm just wondering about what everyone here (including myself) who MUST have a cat on their exhaust has used and acheived best results with. I want to use a Dynomax super converter (13" long, 2 1/2" in/out). But I'm wondering about what everyone else has used.

cardboard paper towel tubes filled with polyfill and steelwool coated in mayonaise and a sparkplug hanging out one end.

Ok ok heres a real answer, when i had my 89 firebird 2.8 v6. i put on flowmaster cats....made it sound like a dirtbike (of course a little bigger, but damn close) when i would rev it up. and it popped like crazy when the rpms dropped. Never had a problem passing emmisions...and i think the flowcat was like 120 bucks or around there. This was back in '97.
